Thanks. FWIW, this turtle library predates several significant improvements to the GUI system, back when a black line (of the kind it draws) meant a precise series of black pixels and a white line meant the same precise series of pixels, but this time drawing them in white .... Nowadays that's not what it means and so the strategy of erasing by drawing in white is not such a good one anymore. I'm not sure there is really a good thing to do here, but I agree that drawing with a 2 pixel wide pen is probably a better than other options.
